Abstract

A method for backing up data in a data center, device and system are provided. The data in all the VMs of one data center can be backed up simultaneously, and the associations between the VMs are also backed up during the backup, so it is unnecessary to concern the recovery orders of the VMs when the data of the data center is recovered. Meanwhile, when the stored data is exported from the hypervisor node, it is unnecessary to notify the upper layer OS for a backup, thereby improving the data backup efficiency and reducing the system logical complexity.

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a continuation of International Patent Application No. PCT / CN2011 / 077945, filed on Aug. 3, 2011, which is hereby incorporated by reference in its entireties.FIELD OF THE INVENTION

[0002] The present invention relates to the field of IT, and particularly to a method for data backup of a data center.BACKGROUND OF THE INVENTION

[0003] With the development of the communication technology, more and more data centers employ the virtualization technology, which abstracts and then rearranges the computer system hardware, and a virtualization software layer runs between the computer hardware platform and the Operation System (OS). The virtualization software layer is generally called as hypervisor and capable of running multiple OSs on a plurality of computer hardware platforms.

[0004] A data center employing the virtualization technology no longer runs a single operation system, thus the backup and deployment for the data center gra...
